1.55" Spotted Phantom Amethyst Crystal with Epidote - China

This is a beautiful, 1.55" wide amethyst crystal featuring clusters of epidote and red-purple spotted phantoms caused by hematite. Some epidote is also included within the quartz. It comes from the Hongxizhen unnamed mining area in the Sichuan Province of China.

This specimen has been mounted to an acrylic display base.

Amethyst is a purple variety of quartz (SiO2) that owes its violet color to natural gamma irradiation, iron impurities, and the presence of trace elements, which result in complex crystal lattice substitutions. It is considered a semi-precious gemstone, and just two centuries ago was considered to have a value on par with diamonds, sapphires, and rubies. The largest and best known amethyst deposits occur in southern Brazil and Uruguay, where they are found in hydrothermally-formed geodes, but many localities around the world produce an amazing variety of amethyst crystals and formations. They are almost always formed in medium- to high-temperature geological settings.
